 ** Test socket IO timeouts
 **
 **
 **
 **
 ** Modification History:
 ** 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
 **	         The debug mode will print all of the printfs associated with this test.
 **			 The regress mode will be the default mode. Since the regress tool limits
 **           the output to a one line status:PASS or FAIL,all of the printf statements
 **			 have been handled with an if (debug_mode) statement.
